Service Descriptions
Comprehensive BMW brake fluid flush using BMW-approved DOT 4 or DOT 4 LV fluid. We exchange old fluid from the master cylinder, ABS/DSC hydraulic unit, and calipers, then bleed to a firm pedal. This restores boiling point, protects ABS valves, and maintains precise braking performance.
Brake fluid in BMW vehicles absorbs moisture over time, lowering its boiling point and risking vapor lock, brake fade, and internal corrosion. This is especially critical in performance-oriented cars exposed to spirited driving, stop-and-go traffic, or track days. Our service uses a pressure-assisted exchange through the reservoir, ABS/DSC unit, and caliper bleeders to remove degraded fluid. We then bleed each wheel in the BMW-specified sequence, cycle the ABS/DSC unit with ISTA diagnostic tools, and verify pedal firmness. We also inspect hoses, fittings, and calipers for leaks. This service restores reliable brake feel, protects sensitive ABS/DSC components, and ensures confidence under all driving conditions.
Service Milestones
If service history is unknown, begin with a full flush to establish baseline fluid quality.
Every 2 years or 20,000 miles to maintain ABS/DSC performance.
For track driving, mountain roads, or humid climates, shorten interval to 12–18 months.
Flush if moisture test strip fails or fluid appears dark/contaminated.
Always flush after replacing calipers, lines, or master cylinder.

Why San Antonio BMW Owners Choose Us
Hear From Our Clients
I had the front left and right control arms replaced and alignment performed on my 2012 BMW 328i. The Bavarian Auto team performed the work in the amount of time they told me and the car was ready as expected. My car handles much better now. I was very satisfied with the work they performed, and it was done in the amount of time they told me. Bavarian Auto Repair is the only shop I take my BMW to and highly recommend them to any other BMW owner.
- Google ReviewThey are total pros from the minute you walk in. Their post report on work they did on my X5 and recommend to have done is very good info. I will be going back for my normally scheduled maintenance.
- Google ReviewStaff was very friendly and professional. The shop is very accommodating and transparent with their customers. I went in for a brake fluid flush, but they found some other issues that were requiring repair. Instead of trying to make a quick buck and convincing me all the repairs needed to be done right then and there, I was told which issues were more urgent and which could wait and was in no way pressured to get any of them done that day. I was also provided with quotes for said repairs with part numbers listed. This establishment truly has their customer’s best interest in mind. They provide outstanding quality work at an affordable price. A trusted dealer alternative for any BMW owner. 10/10 recommend.
